Safe mode on Windows helps to fix problems or to remove malware from the system. Booting Windows in safe mode can be done by tapping the F8 key when the PC starts. Booting a Windows PC in safe mode should not be attempted without prior experience or technical expertise.
Safe Mode is a component of Windows that allows you to access your Window's interface without having to load unnecessary drives and software. It is the diagnostic mode of Windows. When you start your computer in Safe Mode, only specific components needed to run the operating system are loaded.
This implies that:
Safe mode does not allow certain functions, like connecting to the Internet for example
It also loads a basic video driver with a low resolution, which is why the screen may look different to usual
The desktop icons may also have changed location because of the low resolution
Why restart in Safe Mode?
Some malware files are impossible to remove because they are already running. In Safe Mode, only the necessary files are loaded and malicious files can be removed.
How to start in Safe Mode with Windows XP, Windows Vista and Windows 7
It is easy to get into Safe Mode. It is done while you are switching on (booting) your computer.
Use this method only if you have a single operating system (Windows XP, Vista or Windows 7) installed on your computer.
Restart the computer. The computer begins processing instructions known as the Basic Input/Output System (BIOS). The display depends on the BIOS manufacturer. Some computers display a progress bar referring to the BIOS.
At the end of loading the BIOS, start tapping the F8 key on your keyboard (or F5 if F8 does not work). Do this until the advanced options menu of Windows appears. If you begin tapping the F8 key too soon, it is possible that some computers display the message "Keyboard Error". To resolve this problem, restart the computer and try again.
Using the arrow keys, select "Safe Mode" menu and then press Enter.
If you are on a network and your system requires that you are connected to the other computers or to the Internet, choose Safe mode with networking option. Note that dial up connection users will not be able to use this option in Safe mode.
